Uncovering the Truth: New Measurement Challenges Supersymmetry Theories

In summary, recent measurements have dealt a significant blow to theories of supersymmetry, a popular idea that suggests the existence of twin particles for every known particle. While some basic models have been ruled out, more complex models still predict the possibility of an undiscovered electric dipole moment. However, experimentalists face a long and difficult task of testing and potentially disproving these theories.

maybe no supersymmetry...

"The new result deals a significant blow to many new physics theories, most notably supersymmetry, a favored idea that suggests each known particle in the Universe has a supersymmetric twin particle that has yet to be discovered"

"Although some basic models of the theory have been ruled out by the latest measurement, more-complex models predict a small electric dipole moment that could be hiding in the range physicists have yet to search. “You can endlessly make models of supersymmetry,” says Eugene Commins, an emeritus professor of physics at the University of California, Berkeley, who led the last search for the dipole moment in atoms. “A good theorist can invent a model in half an hour, and it takes an experimentalist 20 years to kill it".http://www.nature.com/news/electron...ashing-hopes-for-new-physics-theories-1.14163

1. What is supersymmetry?

Supersymmetry is a theoretical framework in physics that proposes a symmetry between particles with different spin. It suggests that every fundamental particle has a partner particle with a different spin, and these particles have the same mass and internal properties.

2. What are the new measurement challenges in uncovering the truth about supersymmetry theories?

The new measurement challenges in uncovering the truth about supersymmetry theories include the need for higher energy collisions at particle accelerators, more precise measurements of particle properties and interactions, and the development of new theoretical models to explain experimental data.

3. How does supersymmetry relate to the search for new particles?

Supersymmetry predicts the existence of new particles, such as the supersymmetric partners of known particles. These new particles could provide answers to questions about the fundamental nature of matter and the universe, and their discovery would greatly impact our understanding of physics.

4. What evidence do we have for supersymmetry?

Although there is no definitive evidence for supersymmetry yet, there are several experimental observations that are consistent with its predictions. For example, the existence of dark matter, the hierarchy problem in the Standard Model, and the unification of forces at high energies all have possible explanations within supersymmetry theory.

5. How is supersymmetry linked to other areas of physics?

Supersymmetry is connected to many other areas of physics, including string theory, cosmology, and quantum gravity. It also has implications for the study of the early universe and the nature of space and time. Its potential connections to other areas of physics make it an exciting and active area of research.
